BACKGROUND OF THE INVENTION

This invention relates to backpacks, more particularly, a backpack having a semi-rigid container capable of being molded in the shape of a user's back, an angled floor, crisscrossing front straps, a lumbar support, lateral supports with vertical support notches and a waist belt having a buckle.

Backpacks are commonly used to carry loads for many different purposes. For example, students use backpacks to carry books to and from school while hikers and military personnel and use backpacks to carry gear and supplies.

Currently, backpacks include two shoulder straps wherein the wearer places his/her arms through each strap and wears the carrying compartment on his/her back. Although this permits a wearer to carry a large amount of weight on one's back, oftentimes the wearing of these particular types of backpacks results in spinal, neck, posture, and muscle problems caused by improper support and distribution of weight carried on the back.

Thus, a need exists for a backpack that promotes proper posture and spinal alignment of the wearer and, therefore, reduces the amount of spinal, neck, shoulder, headache, and muscle problems a backpack wearer could incur from the load being carried.

The backpack 1 of the present invention, shown in FIGS. 1-3, features a container 2 having a floor 3, a contacting side 4, an aft side 5, a first lateral side 6, and a second lateral side 7. Access to the container 2 is provided by any suitable means, such as a zipper, clip, snaps, Velcro®, etc. The floor 3 of the container 2 is oriented at an angle to achieve optimal weight distribution and stability. In the preferred embodiment of the invention, the container would be constructed out of a semi-rigid material, such as rubber, plastic, resin, or any other suitable material, and the contacting side 4 would be molded and contoured to the shape of a user's back so as to match the curvature of the spine. The contacting side would be thick enough to protect the wearer from any objects being carried inside the container. The container 2 may have small holes/receptacles 8 used for air circulation as well as for attaching decorative accessories 20 as shown in FIG. 5 and FIG. 6.

Referring to FIG. 1, a first shoulder strap 9 and a second shoulder strap 10, which may be molded into the backpack out of the same semi-rigid material used to mold the container 2 or attached as separate components, are connected to the top corners of the container 2. The shoulder straps 9, 10 should be at least two inches wide to allow for even distribution of weight across the shoulders and chest. Adjustment straps 11, 12 are attached to the shoulder straps 9, 10 and connect the shoulder straps 9, 10 to the lateral supports 14, 15. The adjustment straps 11, 12 may be either fixedly or removably attached to the backpack 1 by any suitable fastening means, such as clips, snaps, etc. The first shoulder strap 9 would crisscross the second shoulder strap 10 forming an X across the user's chest, as seen in FIG. 4, allowing for even distribution of counter-support pressure across the user's chest and shoulders and limiting any side to side motion of the backpack while also pushing the shoulders and chest back bringing the head and neck into proper alignment.

In the preferred embodiment of the present invention, the container 2, shoulder straps 9, 10, the lateral supports 14, 15, and the lumbar support 13 are all molded into one unit out of the same semi rigid material allowing the backpack 1 to be manufactured in different sizes to match the contour of a user's torso according to height, or to be custom molded to a specific user's torso.

As shown in FIG. 1, storage pockets 21 used for storing pens, pencils, cell phones, etc. may be molded into the shoulder straps 9, 10 and/or the lateral supports 14, 15 out of the same semi-rigid material used to mold the shoulder straps 9, 10 and/or the lateral supports 14, 15. The shoulder straps may be customized by adding an attachable medallion 22 as shown in FIG. 1 and FIG. 4. The medallion 22 may be personalized for certain groups such as schools, sports teams, etc.

A first lateral support 14 and a second lateral support 15 which may be molded into the backpack out of the same semi-rigid material used to mold the container 2 or attached as separate components and located on opposite sides of the lower portion of the contacting side 4. A waist belt 18 is attached to the lateral supports 14, 15 and is securable by any suitable fastening means, such as a buckle 19. When secured together by the buckle 19, the waist belt 18 fits around the waist and pelvis of the user securing the lateral supports 14, 15 against the sides of the user's body further limiting any side to side motion of the backpack 1 while in use. Vertical support notches 16, 17, molded into the lateral supports 14, 15 are secured against the ilium of the user providing vertical support while also limiting front to back motion of the backpack, and enabling a wearer to carry more weight without adversely affecting the wearer. The waist belt 18 is preferably adjustable via a strap adjustment means so as to provide a tailored fit for the user. A lumbar support 13 may be molded into the container 2 out of the same semi-rigid material used to mold the container 2 or attached as a separate component on the lower portion of the contacting side 4 between the lateral supports 14, 15 so as to fit into the lumbar lordosis and provide support to the user's spine.
